What is Pydantic in Python?

Pydantic is a data validation and settings management library for Python, using Python type annotations.

How does Pydantic handle data validation?

Pydantic validates data by defining models with type annotations, ensuring that the data conforms to the specified types.

Can you give me an example of a Pydantic model?

Sure! Here's a simple example:

from pydantic import BaseModel

class User(BaseModel):
    id: int
    name: str
    email: str

This defines a User model with three fields.

What happens if the data doesn't match the model?

If the data doesn't match, Pydantic raises a validation error, providing details about what went wrong.
